The San Francisco-based producer and DJ will be debuting a brand-new stage setup for this year's show, with a rotating stage placed in the center of the arena.

Last year's concert was a speedy sellout, so take note: tickets for the Dec. 31 concert are $51.50 and go on sale at 10 a.m. Fri., October 19 through Ticketmaster (www.ticketmaster.com, 1-800-745-3000) and the Bridgestone Arena Box Office.

Organizers say the expanded grounds will allow more room for side attractions, including a carnival ride, art installations and "live theatrical elements." WYF has also added two new acts to the bill: Eliot Lipp and TWO FRESH.

The two-day festival takes place October 26-27 at the Lawn at Riverfront Park. Electronic dance music stars Skrillex and Pretty Lights headline the fest along with hip-hop veteran Nas, pop shape-shifter Santigold and more.
